DAVENPORT WALL-BED.

Specification of Letters Patent.

Patented Dec. 15, 1914.

Application led November 19, 1912. Serial No. 732,385.

To all whom t may concern Be it lmown that I, WILLIAM WESTPHAL, a citizen of the United States, residing at Los Angeles, in the county of' Los Angeles and State of California, have invented a new and useful Davenport Wall-Bed, of which thefollowing is a specification.

This invention relates to a bed of the type known as a davenport bed that is adapted to be folded to serve as a sofa or lounge when not in use as a bed and includes a davenport which is capable of being built into the wall as a wall bed and is also capable of being detached from the wall and simply placed against the same as with a common davenport bed.

An object of this invention is to provide a davenport bed which can be opened and closed with minimum labor; which will have an uninterrupted spring support when opened in bed form; and which wlll give a broader bed surface when opened than heretofore provided for davenport beds havin1r the same width of seat and height of bac when closed.

A further object of the invention is to provide a davenport bed in which the connecting means between the seat back` frame and base may with facility be completely concealed from view, thus annihilating the possibility'of injury to the attendant or to children from the exposed connecting means when the seat back frame is being moved.v

A still further object ofthe invention is to provide a davenport bed in which the connecting means between the seat back frame and Ibase can with facility be concealed from view to add to the appearance'of the device.

Another object is to construct a davenport bed which can be opened and closed with minimum movement of the hand.

A further object is to make a davenport having the foregoing advantages and being light and easy to handle, to open and close and to move about.

The accompanying drawings illustrate the invention.

Figures 1 and 2 are front and end elevations respectively, of the invention as embodied in the form of a davenpornt bed applied in seat form against a wall, a portion of which is shown in sectional elevation. Figs. 3 and 4c are front and end elevations analogous to Figs. l and 2, respectively, showing the invention applied as a built-in wall bed. Figs. 1 and 3 are in reduced scale. Fig. 5 is a broken end elevation of a davenport bed constructed in accordance with this invention and viewed from line :v5- m6, Figs. 8 and 9, looking in the direction of the arrows. Solid lines show the bedin seat form, while dot and dash lines indicate a position assumed by parts while they are being turned into bed form. Fig. 6 is an elevation partly in section viewed from line m5--", Figs. 8 and 9, the device being shown in bed form in solid lines while .dot and dash lines indicate a position of parts justbefore reaching said bed form. Fig. 7 is a fragmental enlarged perspective detail illustrating a feature of the operating levers. Fig. 8 is a plan View showing parts in bed form with the mattress folded and strapped upon one of the frames preparatory to turning the frames into seat form. Fig. 9 is a .broken longitudinal section viewed from line x9, Figs.2 and 5, with parts in seat form. i

Broadly considered, the invention comprises a pivotally mounted reversible back frame l that serves as a back for a seat and is convertible by movement on its pivot into a frame for a bed bottom; a pivotally mounted reversible seat frame 2; said frames being mounted and connectedtogether to turn simultaneously to change the device from bed form into seat form and vice versa, there being means connecting the lower ends of the back frame with the seat frame to cause the one to simultaneously turn with the other from their respective normal positions at rest, said means havingy pivotal connection and being entirely positioned at a level lower than the base of the seatwhen the back frame is in erect position as will now be more fully explained. As a support for the back frame l and seat frame 2 there is provided a base 3 having ,a box-like chamben 4 that is bounded by a front piece 5,end pieces 6 and a floor 7. Td the said base there is hinged by hinges 8 at the tops and rear edges of the end pieces 6 a convertiblel back` and bed bottom frame 1. 4Said frame l is provided with a seat-back cushion 9 on one side and a section of bed springs 10 on Ithe other side. A space ll behind the base is closed at the top by a top piece l2 extending across between end portions 13 and 14 that are secured to the end pieces 6 by means of'bolts 15. Said end portions 13 and 14 to close the space 11 at the front therev of when the frame 1 is in position to form the seat-back, or horizontally between the arm rests 16 and 17 when the device is adjusted to form a bed.

To the top of the front piece 5 of the base 3 is hinged at one edge by hinges 18 the convertible seat and bed-bottom frame 2 that is provided on one side with a resilient cushion seat 19 and on the other side with a section of bed springs 20. It is thus seen that the reversible back frame is hinged to said base by hinges 8 at one side thereof and that the reversible seat frame 2 is hinged by hinges 18 to the base at the other side thereof and at a higher level than' the back frame is hinged. blaid frame 2 with its seat and bed springs is adapted to extend horizontally between the end portions 13 and 14 upon the inside of the front piece 5 when in seat form and horizontally in an invertedposition upon the other side of the front piece when in bed form.

The free edge of the frame 2 is provided with the flexible loop a by which it may be manipulated in the operation of opening and closing the bed.

A mattress 21 is adapted to be folded and strapped upon either of the spring sections 10 or 20 to the frames 1 and 2 respectively, preferably upo'n the seat and bed bottom frame 2, and to this end I provide a plurality of straps 22 secured to one side of said frame 2 and adapted to extend over the mattress 21 and into engagement with hooks 23 mounted upon the otherside of the frame. y

Compound lever connecting means are provided between the base 3 and the frames 1 and 2- to transmit motion from one to the other of said frames.y Said means are corre-- spending sets of levers mounted at the ends of the bed between the inside of the arm rests 16 and 17 and the end pieces 6; and to provide space for the operation of said means a filler block 24 is interposed and clamped in place by the bolts 15 between said arm rests and the end pieces 6 at each end of the bed.

The connecting means between the base and the frame 1 upon either end of the bed comprises a fulcrum link 25 pivoted at 26 to the end piece 6 of the base 3 and a connecting link 27 pivoted to the frame at 28, the

free extremities of said fulcrum link andv the base and the seat frame 2 comprises a The connecting means between collapsible `connection 30 consisting of a member 31-pivoted at 32 to the end piece 6 of the base 3, a member 33 pivoted to the seat frame at 34, and a pivot 35 connecting said members 31 and 33. Means are provided to connect the pivots 35 and 29 comprising a support 37 pivoted to the base at 38, a link 39 having one end mounted on the pivot 35 and the other end on pivot 40 at the upper end of said support 37, and a connecting bar 41 between the pivot 40 and the pivot 29.

A stop 42 is provided upon the member 33 adjacent the pivot 35 adapted to engage the link 39 to arrest the alining movement of the members 3l and 33 as the frame 2 is turned on its hinge 18. In order to gain the most direct and precise action of parts in the form illustrated `in this application, it is desirable that the link 39 be practically horizontal at all times and to this end the pivots 32,38, and 40 are arranged at the corners of a parallelogram so that as the arms 31 and 37 are moved forward or backward as hereinafter described upon their pivots 32 and 38the link 39 remains parallel with the pivots 32 and 38 that are substantially in parallel alinement with the floor 7. 'l f A supporting plate 43 is secured to the bed spring side of the frame 2 at the ends thereof, extends outwardly therefrom, and is adapted to seat .on the points formed at the pivots 29 between the fulcrum links and connecting links 27 at the ends of the bed, to thereby support the frame 2 in its seat form as shown in Figs, 53 and 9.

Means are provided to support the seat frame 2 in its bed form comprising legs pivoted at 44 at the ends of the frame; said legs being provided with. slots 45 in which are slidably mounted pivot ends of connecting rods 46 pivoted at their other ends to the members 33 'between the pivots 34 and 35 thereof.

At the ends of the frame 2 are provided brackets 47 upon which the legs 44 are adapted to rest when in the folded position they assume whenever the member 2 is in seat form.

Spring means to ease the frames 1 and 2 into seat or bed form are provided preferably in the form of a helical spring 43 that may be attached to the frame 1 and base floor 7 by means of screw eyes or staples 49 and 50 respectively.

The hinges 8 for the convertible seat back frame 1, are located above the bottom edge of said frame so that when the back is in upright position, the height of the back above the base will not be the full widthof the frame but when in bed position, the full 1erv width ofthe frame will be used. This is of of the bed need not be decreased in order to obtain a seat bach of proper height. Furthermore, the spring 48 is connected to the lower edge of said frame 1 considerably below the hinge S so as to have as great leverageas possible upon said frame to assist in counterbalancing the parts as operation thereof is effected.

When the bed is folded in scat 'form the legs 44 rest upon the brackets 47, and support the connecting rods in folded position as shown in Fig. 5; and the frame 2 with .the mattress attached thereto is supported on the joint formed by the pivot 29 upon which the bearing plate 43 rests; said mattress being housedin the chamber 4 that is provided for that purpose. j f

The frame 1 with its spring section 10 stands on edge between the end-portions 13, 14 to close the recess 11 when the device is in seat form.

In practical operation the device may be turned from seat form into bed form by pulling up the loop a, thereby turning the frame 2 on the hinges 18. This movement increases the distance between the pivots 34 and 32 causing the members 31 and 33 to swing rearwardly abouttheir pivots 3,2 and 34 toward an alined position with one another, thereby moving the pivot 35 rearwardly, and acting through the connections 39, 37 and 41 in turn moving the-.pivot 29 to extend the frame l backwardly upon its hinges 8 and into the space 11. This'backward movement of the member 1 acts only as a compensating movement while the member 2 is being substantially raised on edge as indicated by do't and dash lines in Fig. 5; and as the movement of the joint :1t the pivot 35 continues by reason of the further turning of the member 2, the stop 42 engages the under side of the link Il!) to prevent the members 33 and 31 from coming into alinement 4with one another, thereby arresting the rearward movement of the pivot 35, and upon a still further turning movement of the member 2 moves the pivot n 35 forwardly by collapsing the members 31 and 33 as the distance between the pivots 32 and 34 decreases. This forward movement of the pivot in turn acts upon the pivot 29 through the said connections 39, 37 and 41 to bring the member 1 forwardly upon its hinges 8 until arrested by the end pieces 6 of the base. During this time the frame 2 with folded mattress attached thereto, has been turned into the horizontal position shown by solid lines in Fig. 6,' and the leg 44 has arrived in position to support the frame 2, having been extended into said position during the downward movement of the frame 2.

With the frames l and 2 now opened into.'

bed form, the folded mattress 21 may be un- .strapped fromthe springs 20 of the frame 2 and the folded over portion laid upon the i springs 10 of the frame 1, thereby forming a bed with an uninterrupted spring support and mattress thereon. r l

When it is desired to turn from bed form back into seat form, the operation just described is reversed.

The construction of the operative parts is practicall i the same in the detached as in the builtlm construction, there being in the latter, a recess 148 being formed in the wall 149 to receive the seat-back and bed bottom poillsion; and the arms being fixed to the wa It is understood that various forms of means connecting between the frames 1 and 2 may be provided to cause the one to simultaneously turnvwith the other and this invention is regarded as pioneer in that the seat-back and theseat bottom are connected to simultaneously turn from seat form to bed form as herein disclosed.
